v v @we Theconstruetion shown 1n the-drawings' l has two principal frames, one o'f \vl1ieh I shall term the Wheel frame and the other: the

plow frame. Although some'of the. parts may be found in earlierplon-'s, l. will briefliy note them here, that the novel features may be fully understood. The'wheel frame. is formed of tivo bent parts 1 and Q, the bar 1 being shaped to have the longitudinally` extending part 3 Vwith the cross bar4 at the front, extended laterallyv asA at .5, Aand the backward turned bar 6 at thel rear. The other bar 9,', ofl this wheel frame or main frame, is shaped to have the inclined rear part T and the l-fugitndinally arranged part V 8, the rear end of ,this alsobeing bent baclr- A ward for a short distance. At the front enid it is turned laterally at and rigidly secured to' the front part' l of the etherbar. This frame is supported upon the three 'wheels 10, 11 and 12, that at 10. being a front stag- Vgered, or inclined, furrow wheeh-that at 11 Specification of Letters Patent.

This comprises longitudinal bars :such asare g5 vshown at 42, 43, 4 4, connected attheir front. .ends by cross brace bars 15 and at theirrear ends by the inclined cross vbar 4G, lQmfiucreasing Vthe strength and stiffness 01E-fthe frame supplemental brace-bars can be usedo as shown at 47. Upony this fraxneand; mounted transversely.'the eofare-the Cra'ni' shafts 4S and 49;' 'lhje,forwardera-nkrshaft 4:8 is mounted in boxes zit-'.50 on the Yframe bars 42, 14, and vthe rear eran l asliiftyil is being Carried b v" the reaeincli-n'ed bi These Crank shafts; 'hare bearings also on the wheel 'frame or lmain fi'axnewthegbo es the front shaft being shonn' -at 5 3, those for the rear 'sha ft atflra'; .5&1 frame, non' being' described` are-see standards and the plow bodies l'.

The plows and the plo'n"lrame'w reetly supports them, are raised and ll ed in horizontal parallelism. he raidirof lthe Cranl-:sof tbe front shafts beingr substalr tially equal to the radii of the rear orauks. The two shafts are tle \"ibl Connected together in a way to bedescribed so tl1a t they 110 will vibrate simultaneouslyl andin substantialv unison. The land wheel 12 is supported upon a spindle 55, this wheel having a toothed wheel l66 secured to it at the inner end of its hub 67, which toothedwheel is for a purpose to be set forthbelow. .The spindle' 55 is carried -bya radius arm 56, which at-57 is connected to the rear crankshaft 49, there being a lateral'e'xtens'ion of this shaftat 49l rejecting toward the land side beyond the 011531 which connectstthe crank Shaft to the wheel frame.

a plate secured to thls shaft extensioniand hav-ing a recess at 58 in whichtheradiiis arm 56 is situated.

-59 is a ratchet segment at the edge of the plate 58. f 60 is a lifting lever pivoted .to the plate 58 and having its short arm 61 con nected through a link or links 62 Ato the radius'arm 56, and this lever yhas a springactuated deten't engaging and interlocking with the teeth of the segment at 59. Power' can be-eXerted through the lever 60 in such way as to cause the radius arm 56 to move forward or backward in relation-to the plate. 58 and thereby raise or lowerthe .framework upon the land wheel as is indicated by the relative positions of the wheel-frame and shaft 55 1n Figs. 4 and 5f {fllhe plow frame and plows can be raised*v lor; lowered in relation to the main fra-me or wheel f rameby-either oftwo sets of devices, respectivel vconstructed and operte'd as follows. 68 1s a hand lever connectedfto theVA rearcrank axle by means `of- .a bracket castf ng'69. If the lever be pushed forward itrocks the crank shaft 49, 49a`inthe bearings 53, 54 and throwsthecranksand the intermediate'part of the shaft upward thus lifting' the rear end of the plow frame and the plows. Such rocking forward of the crank shaft 49,49, throws backward the i to rise, which results in lifting the vfront end plate 58; v llhis plate is connected by the-link 0 tol thecrank lon the end of the forward crank shaft 48 'and consequently when the plate 58 swings back' it causes the cranks of` the crank shaft and thecentr'al part thereof of the plow frame, and as the two crank shafts are, by the devices just referred to each operated in unison, plow frame rise and fall-simultaneously.

At-the time theplows and plow.- frame reach the uppermost point of their travel,

the det'entf at 72l on the lever '68 enters a recessin the lock segment 74 and engages wlth a shoulder.' at 7 3j which prevents the lever from moving in the opposite direction and most position in relation to the main frame, they wel; "it 76 'I hacensstslof erin snr holds the crank shafts against downward movement. The detent 72 is connected with a thumb latch 75 by which it can be released at will. l

When the' plows are down in their lowerand the plow frame;4 are locked bythe both 'ends ofthev 77 with which engages a coiled spring 78,

these parts being carried by a lbracket 79 leasedby a foot trip having the trip arm or crank arm 80 carried by the shaft 81 sup-A ported at vits inner-end in the metal of the brackets 69, 79, and at its outer end sup cast with the bracket 69. This lock is reported in a bearing at 82 formed on the aforesaid plate 58. The shaft 81 has a crank arm 83 shaped' toprovide a pedal 84 by which the operator can, with his foot, rock the shaft in such way as to releasethe llock -pin 77. I

The other set of devices (supplemental to crank 83 Yof the shaft 81 by means of the link 88. lVhen the shaft 81 is rocked by force applied to the pedal 84, the link 88 transmits motion to the bolt 85 and thrusts its lower end 'into the path of the 4toothed wheel 66. 'The 4instant the wheel engages with this bolt its rotation is stopped andthe draft of the team now-.transmitted to the 'wheel compels it to force theradius arm 56 backward and as this plate is, through the' lever 60 and the detent and segment 59 rigidlylocked with the plate 58, the latter is also thrust backward and the crank shaft 49, 4911 isrocked in such manner as to cause the plow frame and the plows tobe lifted. And the link 70 being pivoted to the plate 58, the lifting force is transmitted. also to the front crank shaft which lifts the' front end of the plow frame. The pressing down ofthe bolt- 1 85 by the treadle 84 follows quickly after the loosening of the lock-77.

90 is-a coiled spring combined with thel bolt 851 and tending to thrust it upward to insure quick disengagement. gagement willoccur .instantly after the op--- erator removes his foot from the pedal which i he 'does as soon as thelever 68'hasreached This disenthe position where it is lockedagainst the shoulder 73 on the segment bar`74.

The devices which'lift the plows are :issisted by one or more springs. One is shown at 97 having Aits rearA end connected at 98 to the frame, and its front end connected to an extension 99 of. the hand lever 68. Preferably the spring or springs and attachments are so arranged that they` wlll exert a reduced force when the .plows are in -their workingl position, but lwith Aan increasing A forceafter the plowshave been started up .l
